I know someone who has sparc, alpha hardware. I'm not sure if they
have an ia64 box taking up space in a closet somewhere.
A core advantage for ppc32 is that one can still readily get hardware
for a quite reasonable price locally or on EBay.
Because of branding, I would certainly prefer that ppc32 remain under
the Fedora umbrella as a seconday-secondary tertiary architecture
rather than be forced to become a remix.

I hope that we can prevent things from becoming as hopeless as sparc
and ia64. Being a viable separate secondary arch for older hardware
is certainly a better fate than a dead tertiary arch.
Some folks have volunteered to host the builds, and provide build
hardware. We'll see how that works out. If we do have to build outside
the Fedora systems, there are going to be security considerations.

Trying. I likely spent too much time gathering a representative mix
of hardware. Lesson learned.

Thanks for clarifying that.
The problem with dropping smp is that I and other have smp hardware
that we would like to use. That is also likely the hardware that
would best be used for builds, should "build native" and lack of a
ppc32 cross compiler & binutils mean we can's use a ppc64 build host.
